OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 267,584, dated November 14, 1882.

Application filed March 29, 1882.

1'0 all whom it may concern Be it known that I, UHARLES J. PINKNEY, of Cleveland, in the county of Ouyahoga and State of Ohio, have invented a new and useful 5 Improvement in Oil-Cups, of which the following is a specification.

The nature and objects of this improvement willfully appear from the subjoined description, when considered in connection with the accompanying drawing, in which the figure is a vertical section.

This improvement consists in making a seat in the bottom of the cup over and leading into the discharge-opening in the supporting-stem,

and employing a ball-valve for closing the same. 1

A is the bowl or body of the oil-cup, and is rovided with a suitable cap or cover, B, and a neck or stem,G, by which it may be attached to the parts which it is intended to lubricate, the neck 0 having a vertical central opening, 0. The junction of the said opening 0 with the bottom of the interior of the cup forms the valve-seat. The valve consists of a ball,

D, which lies over the said opening 0, and serves as a cut-off to the opening and prevents the passage of oil while the cup is at rest. The ball may be made of any suitable heavy material, preferably of glass.

0 The operation of this device is as follows: By the jarring of the ball, which is caused by the movements of the machinery to which the cup may be attached, the opening 0 is sufficiently uncovered to allow of the escape of 3 5 small quantities of oil, suffieient for lubricating purposes,

This oilcup is especially designed for lubri- (No model.)

eating the slides of loeomotiveengines, the jarring of the ball by the movements of the locomotive being quite suflicient to allow the 0 cup to discharge the required quantity of oil without waste. lt is an economical oiler, for when the machinery is at rest theie is no discharge of oil. It is not intended for lubricating cranks, cams, or connecting-rods, as the 5 motions would be too great; but it is useful for all stationary slides,journals, and shafting,

as the simple jarring ot' the ball caused by shaking or by the suction of the revolving journal allows the necessary supply of oil to escape for lubrication.

I am aware that it is not new to make an oil-cup with an inner chamber having a rounded bottom and containing a ball which closes the feed-opening in the apex of'the bottom; 5 and that I do not claim. My device,however, differs from that, in that I dispense with the inner chamber and make the oil-cup proper with a rounded bottom. Therefore What I claim as new is- As a new article of manufacture, an oil-cup having an inner rounded base, which forms the bottom of the cup proper, a stem'formed integral therewith and provided with a feed-tube terminating at the apex of the inner rounded 6; bottom, and a ball-valve contained within the cup, and having the inner rounded base for a seat, and closing the feed-opening when the cup is at rest.
